I apologize if this is not the right place for it. I have a laptop with an onboard JMicron ethernet controller. Relevant hwinfo output along with additional system information are included at the end of the message. I am able to change the MAC address using macchanger, ip and ifconfig but I am unable to obtain an IP address via DHCP (using dhcpcd or dhclient) after doing so. Aside from MAC spoofing, everything else works as expected. I have posted more information in a thread on the Arch Linux forum [1]. I have also packaged [2] and tested the upstream Git version of the driver [3], but the issue persists. Does anyone have any idea of how to resolve this? I have looked at the source code but I do not know anything about network drivers. I hope that the solution will be readily apparent to someone who is much more familiar with the code and drivers in general. Any help would be appreciated.
